in the-particular Yeinbodin'lent of the invention illustrated `in Figs. -l Ato-'1,0 inclusive, the ,pencil 'comprises -abarrel i0 -which may Ybe formed of any suitable material, such as Wood or plastic.

Aftip H is secured to thefbarrel yat oneendvthereofythe ytip-having an elongated outer end l2 which'is preferably split and forms a grip'for Vholding the lead-asthe leadisied therethrough. f1-he intermediateportion 1,3 ofthe tip is preferably substantiallycylindrical and forms a sup port for the outer end M oa spiral-tube l5 which forrnsra support for guiding the lead throughithe penciland to the tip.

' The rear end i6 of the'tip is preferably cylindricalandhas formed on its end raised vsegnlen- -tal threads il. The Atip,is'tlireaded into thetip -e'nd of -the barrel i by-rotation in the direction -of ythearrovvshovln in Fig. 9, whichcausesjthe `segmental threads to-fcrrn spiral grooves iny the innersurface ofthe cylindrical end portion of the barrel. Afterthe -tip 1has beenthreadedinto the barrelitcannot-be-turned in the opposite directionand--reinoved sincetlie ends I8 ofthe .segmentalethreards would cut into thefba-rrel sur- Lface andpreveritv such reverse lrotation.

Thelopposite -end Voithespiral tube iii issecured in a disk-2i? which is iziedly secured in a lerrule 2| and it should-be notedgthat the spiral tube which forms the support and` guide rfor the lead extends substantially throughout the .length of the barrel and pencil.

4The rear-.end of the .barrel has a conical seat -23 which receives .a correspondingly shaped conical portion Zi of -a plug25, shown particularly inaFigs. l and 5. The-plug hase cylindrical opening therethrough through which extends the tube I5. The rear end 26 of the plug 25 is spaced from the disk 26 and the ferrule 2| is rotatably mounted around the portion 21 of the plug 25. The plug 25 is xedly secured in the conical seat 23 by any suitable adhesive.

The ferrule 2| has formed on the inner end thereof a bead 36 which terminates in a ange 3|. The plug 25 has formed therein intermediate the portion 21 and the conical surface 24, a notch 33. A conical split ring 34 is secured around the conical portion 35 formed by the notch. When the ferrule is to be secured in place it is moved over the portion 21 and the flange 3| contracts the split ring 25 until the edge of the ange has passed beyond the split ring, whereupon the ring expands inside the ila-nge 3|. Thus the ferrule is held in place.

The lead is fed through the spiral tube I by means of a lead propelling member shown in detail in Figs. 6 and 7. This member has an arcuate portion 46 and a lug 4| extending laterally from one end of the arcuate portion 46. Viewed from the rear, as shown in Fig. 7, the arcuate portion forms wings 42 and 43. The end 44 of the arcuate portion 46, as shown particularly in Figs. 1 and 2 at 45, is curved or pointed.

The barrel I6, as shown in Fig. 4, is provided with an arcuate groove 56 throughout the major portion of its length for guiding the portion 40 of the lead .propelling and feeding member along the outer surface of the spiral tube I5. The lug 4| of the feeding member extends through the spiral slot formed in the tube and engages the rear end of the lead, thus feeding the lead through the tube I5, as shown in Fig. 2.

The plug 25 is provided with a, pair of ledges or shelves 5| and 52 which are adapted to engage the wings 42 and 43 on the leadpropelling and feeding member 46 when when this member is retracted to the extreme rear end of its path of travel, as shown in Fig. 1. As the wings i2 and 43 engage the ledges or shelves 5| and 52, the member 46 will move laterally relative to the tube I5, thus withdrawing the lug 4| from the tube, leaving the rear end of the tube open.

The rear end of the ferrule 2| is normally closed by a reversible eraser cap 55 having an eraser 56 at one end thereof and an ornamental portion 51 at the other end thereof. Intermediate the ends there is formed a. laterally extending collar portion 58.

When the eraser cap is removed from the -ferrule it will be noted that the outer end of the tube I5 is open to receive a lead which is dropped into the opening at the outer end thereof and will drop by gravity into the tube I5 until it engages the rear end of the lead section still in the pencil. After the lead has been dropped in the cap can be replaced and the ferrule 2| is rotated, thus rotating the disk 26 and tube I5. As the tube I5 is rotated the feeding lug 4| will move inwardly into feeding position in the tube as the wings 42 and 43 ride down the inclined ledges or shelves 5| and 52. be fed through the tip in the usual manner.

In the form of the invention illustrated in Fig. l0 the pencil can be loaded without removing any cap. In this form the cap is formed in two sections 66 and 6|.

Section 66 has an internal annular notch or groove 62 which ls adapted to receive a split conical locking ring 63 which surrounds a conical portion 64 of the plug 65 cemented to the barrel I6, A thrust ring 66 is mounted in sec- The lead wll then.

4 tion 66 of the cap and engages the rear edge of the locking ring 63. When section 66 of the cap is placed on the plug 65 and is pushed thereon, the ring 63 contracts into the space around the conical portion 64 until it can snap into the annular recess or groove 62.

'Ihe rear end of the spiral tube 16 extends through the plug 65 and through the portion 1| of the section 66 of the cap and is swaged outwardly or ared at its end 12. The outer or end section 6| is then cemented to section 66. Section 6| has a central opening 13 alined with the tube 16 and flared as at 14 to facilitate the insertion of the lead in the cap and tube.

Thus when the pencil requires a rell, the lead is dropped into the opening in the cap and it is not necessary to remove any cap or other parts.

From the foregoing description it Will be evident that the number of operative parts of the pencil described is held to a minimum and that the lead can be easily and quickly replenished simply by retracting the lead feeding member and dropping the lead into the outer open end of the tube I5.

A slightly different form of the invention is illustrated in Figs. 11 to 16 inclusive. In these figures a barrel 86 has a reduced front end 8| on which is rotatably mounted a sleeve 82 having a tip 83 at the outer end thereof. In Fig. l1 the rear end of the sleeve 82 is shown as bent inwardly at 84 to t a correspondingly formed portion 85 on the barrel.

The spiral tube 86 fits tightly in the front end of the tip 83 and extends rearwardly through a central opening in the barrel but terminates at its rear end to leave a space 81 between a plug 88 and the rear end of the barrel.

A clutch tube 89 is xed in the forward end of the spiral tube 36 and extends through the tip 83, the outer end of the ,clutch tube, as shown at 96, being split to form resilient ngers engageable with the lead 9| `as the lead is fed through the tube 89.

The lead is fed through the spiral tube by means of a feeding member which is shown in detail in Figs-15 and 16. This member has a downwardly extending lug 96 adapted to t in the spiral slot in the sleeve 86 and has laterally extending wings or ledges 91 and 98. The rear end of the member 95 has arcuate upwardly extending lugs 99 and |66 and a lug |6| extends inwardly intermediate the portions 99 and 66 and has a beveled end |62 forming a sharp edge. The lug |6| engages the rear end of the lead and feeds the lead through the sleeve 86. The feeding member 95 moves along-the spiral slot by reason of the engagement of the lug 96 in the slot. This feeding movement is accomplished by rotating the sleeve 82 on the forward end of the barrel or relative to the barrel. This causes the spiral tube 86 to rotate relative to the barrel. The feeding member 95 is held from rotation since the portions 91 and 98 of the feeding member are disposed in a longitudinal channel |65 formed in the barrel and communicating with the central opening therein. 1

After the lead has been fed to its forward eX- treme of movement, as shown in Fig. 11, in which the front end |66 of the feeding member 95 engages a stop shoulder or abutment |61 formed in the barrel, the feeding member is retracted by a reverse rotation of the spiral in the barrel.

At the rear end of thebarrel is secured a plug i f 5| f fsimilarg. infconstruction to.; .the 5. plugZA-.Shown Yin lig. 5. This:plug ghas; abord-extendingtherethrough :and disposed-in.- valinement withzthe rear open 1 end l. of z the spiral :tubetr and, as .shown .particularlyfin .'Figs. 111:.and i12,.;a fspace; I is formed-atztherear :end vof .theaspiralgtube .The plug |||J has ledges ||2 and;|j|3;engageable .by theiportions 91 and-98.ofithefimember'BE as this memberis Nretracted :to l:the position vshown .in Eig. l2. ;Furthermorafit .will-:be noted A.thatthe -recess |,|4 is adapted -'to receive the upper ends of: the portions 99 iand |00 ande toppermit the. lug 56| to. move out of the-path 4ofthe lead ,as vthe leadis.l fed in through the -opening v||5 inthe plug H0. If-,the leadis too long. and extends in back of the initial feeding'rposition of .the-lug MJL the initial feeding.. vmovementof themember ,S5 willcause Vthefedge lllzeat. the yend ;,of .the lug to engage the lead and breakit as. shown inFig.

.1-2. ,The engagement of the lugs .|00 :with surface .and of portion |2| of the member 95 with surface |22 inthebarrel force the-edge |02 tobreak the lead.

In-Ythe embodiment lofthe invention shown in Figs.. 11 to 16, the lead can be easily and quickly dropped linto the opening-|| 5 after the feeding member 95 -has been retracted toythe position sho-Wn in Fig. 12-and the feeding movement will then cause the edge |02 to break the lead to proper length and thereafter tofeed the lead longitudinally through the spiral. It Willvbe obvious that in this embodiment the movement ofthe operative parts of the pencil has been reduced'toa minimum and that the useY of the pencil has been simplified since it is not necessary tounscrewor'open upthe rear end of the pencil in order to replenishthe leads but merely to re- .tract the feeding member,drop inthe lead, and then start ythe feeding member on its operative movement.

Although certain specific embodiments of the invention have been particularly shown and described. it Will .be understood that the Yinvention is capable .of vfurther modification and that furtherchanges in the construction and in the arrangement `of the various .cooperating parts may' bemade without .departing from the .spirit .or scope of the invention, as expressed in `the 4following claims.
